Coal fired water tube steam boiler
Automatic operate system
Sufficient combustion;
High thermal efficiency;
Low pollution
Latest scientific research achievements are applied to the new DZ series boiler ,it has new breakthrough in technology.
1.Effective measures are adopted to solve the problem of the boiler tube crack and bulge in the lower of boiler
which always with the common boiler.
2.The optimal design on thread fire tube enhance of the heat transfer ,make the the boiler output fully ,
the pressure and the temperature increase faster.
3.The reasonable design adopted to the furnace arch improves the burning conditions, enhance the dust fall function
of furnace itself and reduce the boiler emissions.
4.Perfect sealing performance, flexible adjustment and reasonable wind distribution of the wind chamber in the furnace,
reduce the coefficient of excess air and increase the thermal efficiency.
5.Light chain grate as combustion equipment ,full-automatic operation,convenient to operate and maintain.
6.We are national A_grade boiler manufacturer with ISO9001 certificate ,have strict quality guarantee system, and perfect sales service.
